The Los Angeles County is providing the following forecast:

RAINFALL
The current estimate is for 1 to 3 inches of rain to fall in the foothill areas between noon Friday  and noon Saturday.

MUD & DEBRIS FLOWS AND FLOOD POTENTIAL
All of the  debris basins have available capacity and no mud or debris flows are anticipated for our area. There is still a potential for debris flows to create issues at the Canyon Crest bridge or for Millard Creek. Please exercise caution when driving on or around the Canyon Crest bridge.

ROAD CLOSURES
As is typical for major storm  events, some road closures are already in force. That includes Angeles Crest Highway, Angeles Forest Highway to Aliso Canyon.

The Forest Supervisor for Angeles National Forest often  announces closure of Chaney Trail at the gate, and closure of Millard Canyon Campground.

The National Weather Service has issued a Special Weather  Statement which also indicates that snow levels for our area will likely be 4,000 to 5,000 feet, with 1 to 2 feet of snow anticipated when the snowfall on Friday afternoon, but is likely to drop to as low as 1,000 feet for our part of the foothills Friday night and early Saturday.

They are indicating that additional roadways may be impacted, including I-5 through the Gorman area, Cajon Pass, SR-14 through the Antelope Valley, Soledad Canyon in the Acton area, and other mountain roadways because of the potential for snowfall a lower elevations.

High winds with gusts to 50 mph may occur as well as  thunderstorms, waterspouts and hail. Stay safe and drive carefully!
